What we build
Popular
Construction & renovation, done properly.
From single-storey rear extensions to full-house refurbishments — we take the job from first measurements to handing over the keys, and everything in between.
Kitchens & bathrooms
Full kitchen and bathroom installs, including knock-throughs, plumbing, electrics, tiling and decoration. Whether it's a sleek modern fit-out or a classic family kitchen — we'll deliver it.
Brickwork & structural
Garden walls, chimney rebuilds, RSJs, steels, openings and load-bearing alterations. Twenty-plus years of brickwork — clean lines, proper bond, neat pointing every time.
Full refurbishments
End-to-end refurbs — strip-out, first-fix, plastering, second-fix, decoration. Perfect for landlords getting a property ready to let or homeowners doing a top-to-bottom refresh.
Roofing & exteriors
Pitched and flat roofs, fascias, soffits, guttering, render and external cladding. We work closely with trusted specialists where the job calls for it — and stand behind the whole package.
Driveways, patios & landscaping
Block-paved driveways, resin-bound surfaces, porcelain patios, garden walls and decking. We do the proper groundworks so it still looks right ten years from now.

"Joaquim and his team did our rear extension — turned up when they said, finished on time, finished on budget. Site was tidy every day. Couldn't recommend them more."
"Got Joaquim in for a full kitchen refit. Took the whole job off our hands — knock-through, electrics, plumbing, the lot. Genuinely lovely guys, brilliant finish."
"Loft conversion done to a really high standard. Honest pricing, no surprises, and they actually answered the phone. So rare these days — can't recommend them enough."
